Yes, pain in the left arm can be a symptom of a heart attack. Other heart attack symptoms
If a person thinks they may be experiencing a heart attack, they should dial 911 or the number of the nearest emergency department for immediate medical help.
Other causes of left arm pain and numbness
Below we give a brief overview of other conditions that present with arm pain and numbness, along with their treatments.
1. Arm artery disease
When the arteries of the arm narrow or become blocked, oxygen-rich blood can no longer reach the arm. Symptoms include:
- intermittent pain that occurs during exercise
- muscle loss in the affected arm
- cool or discolored skin in the affected arm
Treatment of arm artery disease varies depending on the cause. Sometimes lifestyle changes are enough to manage symptoms. For example, if applicable, a person may give up smoking and change their diet to improve their cardiovascular health.
Some people will require medications to treat the condition. In more severe cases, a person may need to undergo surgery to increase blood flow to the arm.
2. Pinched nerve
A pinched nerve occurs due to injury, compression, or damage to a specific nerve. Sometimes, this affects an arm, causing pain or numbness. Other symptoms can include:
The treatment a person receives for a pinched nerve will depend on the severity of their symptoms. For minor pain, a doctor may suggest over-the-counter pain medications, such as nonsteroidal anti-inflammatory drugs (NSAIDs). Other options include physical therapy and supportive devices, such as a splint.
If these treatments do not reduce symptoms, surgery may be an option.
3. Peripheral neuropathy
Peripheral neuropathy occurs when damage occurs to nerves in the limbs, such as the arms. The condition affects up to
The symptoms of peripheral neuropathy include:
Thie condition may result in difficulties moving the arms or a loss of muscle tone.
There is currently no way to reverse nerve damage, so if a person notices early signs that could indicate peripheral neuropathy, they should speak with a doctor right away. If the cause is diabetes, managing the condition effectively can prevent further neuropathy from developing.
4. Cervical spinal stenosis
“Stenosis” refers to narrowing. In cervical spinal stenosis, the part of the spine between the shoulders narrows, applying pressure to the nerves in that area. This
Possible causes of cervical spinal stenosis include osteoporosis and a herniated disc.
To relieve pressure on the nerves, a doctor
5. Elbow trauma
Elbow trauma, or injury, can cause pain in the arm. It is
Resting, applying ice to the affected area, and taking pain medications are usually enough for minor elbow injuries. Depending on the extent of soft tissue damage, a person may need physical therapy to regain range of motion. Injuries such as a fracture or dislocation may require treatment in an accident and emergency department.
6. Hemiplegic migraine
Hemiplegic migraine is a rare neurological condition. It causes symptoms similar to regular migraine, such as a headache and nausea, as well as muscle weakness down one side of the body. A person
If the onset of hemiplegic migraine is sudden and severe, a person will usually take NSAIDs for the pain and antiemetics to prevent nausea and vomiting.
In cases where other family members also have hemiplegic migraine, a person may have inherited familial hemiplegic migraine. For this type of migraine, intranasal ketamine could be an effective treatment option.
Some drugs people use for typical migraine, such as triptans and ergotamines, may not be suitable for hemiplegic migraine.
MS is a condition in which the immune system attacks the sheath that surrounds nerves. This
- loss of sensation, or numbness
- crawling or tingling sensations
- shooting pain that is similar to an electric shock
- a higher sensitivity to pain
Treating MS pain involves medications. The first-line treatment options include certain antidepressants, anticonvulsants, and topical lidocaine. Newer alternatives, such as cannabinoid drugs and neurostimulation,
8. Lyme disease
Lyme disease occurs due to a bacterial infection that certain types of ticks transmit when they bite humans.
The first stage of the disease develops
The second stage of Lyme disease occurs around 3–12 weeks after the bite. At this stage, a person may experience pain, particularly around joints such as the wrist. Muscle aches, headaches, dizziness, and chest pain can also occur.
Late stage Lyme disease can have nervous system involvement, which may result in pain, numbness, or tingling in the hands and feet.
The treatment for Lyme disease depends on the person’s age and the disease stage. People over
Late stage Lyme disease can require longer courses of antibiotics or IV antibiotics.
9. Allergic reactions
A severe type of allergic reaction, known as anaphylaxis, can cause paresthesia — numbness or a burning feeling — in the left arm in some cases.
